CUT-OFF FOR HOSE-NOZZLES.

SPECIFICATION forming part of Letters Patent No. 310,326, dated January 6, 1885.

Application filed February .21, 1834. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, LYIWIAN B. SMITH, a citizen of the United States, residing at Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Out-Offs for lHose-Nozzles; and I do hereby declare that the saine are fully described in the following specification, and illustrated in the accompanying drawings.

The object of this inventionfis to provide a simpler and more effective cut-0H for hosenozzles, faucets, and the like than has heretofore been known, and at the same time to regulate the size of the opening without forming angular crevices or destroying the rotundity of the stream.

My invention consists in a nozzle or faucet having in a suitable chamber a single sliding plate perforated at one side of its center, so as to coincide and be thrown out of coincidence with the tubular water-way, and recessed to receive the pins which move it when the nozzle is partially rotated.

In the drawings, Figure l is a longitudinal section showing the end of a pipeto which the nozzle is attached,and my improved cutoff in position to stop the flow. Fig. 2 shows the valve or cut-olf detached, and Figs. 3 and 4 its two extreme positions, dotted lines denoting the intermediate point.

The pipe A has a terminal cap, B, with an axial perforation, O, and a iiXed projecting pin, D, in its plane outer face, E. From this face an annular flange, F, projects to form the cylindrical wall ofthe cutoff chamber.

G is the valve or cut-off, an elliptical metal plate lying in this chamber iiat against the Its water-way is a-single perforation or recess, H, at one side of the center. It has also two recesses, I I, one of which receives the pivotal pin D, fixed to the chamber, and the other receives a like pin, K, projecting from the smooth disk or collar L, which forms the inner end of the nozzle N, and the remaining wall of the chamber. A coupling, O, in closes the collar L, and, screwing upon the threaded exterior F of the chamber, secures the nozzle to the pipe A. A packing-ring, P, between the collar and the coupling, prevents leakage. tated, the pin K in its collar L carries the valve G, with which it engages, from side to side of the chamber, opening and closing the passage alternately by about aquarter-turn of the nozzle.

I claim as my inventionl. In a hose-nozzle or faucet, a cut-off consisting of a single perforated sliding plate held between parallel walls, and movable laterally between them by a partial rotation of the nozzle or cap, for the purpose set forth.

2. The cap B, having a plane outer face with a central perforation, a projecting pin, and a threaded annular ange, and the nozzle N, with its plane collar and projecting pin, in combination with the recessed sliding cut-ofIn G and an annular coupling holding said flange and collar in contact with the cut-off, substantiall y as set forth.

' In testimony whereof I hereto affix my signature in presence of two witnesses.
